Unlocking Hokage Naruto with downloaded saves

Is this possible? I downloaded a save for both Storm 2 and Generations but the Gen save doesn't seem to work and the Storm 2 doesn't seemed to have unlocked the costume. I already own Generations and Storm 2, but on Xbox and I don't feel like rebuying them just for this costume.

If you've managed to resign the save to your profile then it should (Not 100% sure so to be safe lol) work but I've never really tested this method with games that detect saves from previous/other titles.---PSN - iTzKingTGP (I don't use slang in messages.
